Blueberry × Jack Herer Auto blends Blueberry’s fruity sweetness with Jack Herer’s uplifting cerebral buzz. This 70% Sativa / 30% Indica autoflower hybrid delivers 14%–18% THC and minimal CBD (0.02%), producing a happy, energetic high with light body relaxation. Plants stay compact (around 4.92 ft/1.5 m) and finish in 8–10 weeks from seed.
Yields are modest 0.56–0.66 oz/ft² (170–200 g/m²) indoors but outdoors a single plant can yield up to 28 oz (800 g) in ideal full-sun conditions. Buds exude fruity, spicy, and woody aromas driven by terpenes like Alpha-Phellandrene, Delta-3-Carene, Limonene, and Terpinolene.
Medicinally, it helps arthritis (Delta-3-Carene & Linalool), insomnia (Myrcene & Terpineol), and pain (Myrcene & Humulene). Its autoflower genetics and forgiving nature suit beginners seeking a balanced, quick turn-around crop.
Promos & Deals
Growing Environment
Indoors: Maintain 68–78 °F (20–26 °C) days with a 5 °F drop at night. During veg, keep RH at 55%–65%; lower to 40%–50% in bloom to protect buds and concentrate resin.
Outdoors: Choose a sunny, sheltered area with well-draining soil enriched with compost. Provide six hours of direct sun, and in hot climates offer afternoon shade. In cooler zones, use a simple hoop house to extend warmth.
Ensure good airflow: oscillating fans indoors and 2–3 ft (0.6–0.9 m) spacing outdoors to minimize humidity pockets and deter pests.
Setting Up Your Grow Space
Blueberry × Jack Herer Autoflower Indoor Cultivation
Use a 3×3 ft tent lined with reflective Mylar. Hang full-spectrum LEDs on an 18/6 cycle throughout. Install a carbon-filtered exhaust and intake vent to control odor and maintain fresh air. Place an oscillating fan at canopy level for even airflow.
Grow in 3–5 gal fabric pots with a light soil mix (pH 6.0–6.5) amended with perlite. Autoflowers perform best started directly in final containers to avoid transplant shock. Automate lighting and climate via digital controllers for consistency.
Blueberry × Jack Herer Autoflower Outdoor Cultivation
Plant in raised beds or large fabric pots with a 2:1 soil-to-compost/perlite mix. Space plants 2–3 ft apart. Stake or cage young plants early to support bud weight.
Water deeply when the top inch of soil dries, then allow slight dry-down to encourage root strength. Mulch to retain moisture and suppress weeds. Protect buds from heavy rain during early flowering with a removable tarp.
Seed Propagation and Germination
Soak seeds in distilled water for 12 hrs, then place between damp paper towels at 75–80 °F (24–27 °C). After 24–48 hrs, once taproots appear, plant taproot-down ½ in into moist starter mix under a humidity dome.
Provide 18–20 hrs of gentle light until true leaves form. Remove the dome gradually over 3–4 days to acclimate seedlings to ambient humidity and airflow. Label each pot to track growth.
Blueberry × Jack Herer Autoflower Vegetative Phase
Maintain an 18/6 light schedule. Feed a balanced nutrient (N-P-K 3-1-2) at half strength weekly. Employ low-stress training (LST) in weeks 2–3 to spread canopy and maximize bud sites.
Keep temps at 68–78 °F and RH at 55%–65%. Introduce beneficial microbes early to support root health. Prune lower foliage to improve airflow and direct energy to upper colas.
Blueberry × Jack Herer Autoflower Flowering Phase
Bloom begins around week 4 without altering light cycles. Transition to a bloom formula (N-P-K 1-3-2) to support flower development. Lower RH to 40%–50% and maintain 65–75 °F to boost resin.
Remove large fan leaves around week 6 to expose buds. Support colas with soft ties or netting. Begin flushing with plain, pH-balanced water in the final week to improve flavor and smoothness.
Fertilization and Nutrition
Veg (weeks 1–3): N-P-K 3-1-2 at half strength. Early bloom (weeks 4–6): N-P-K 1-3-2. Late bloom (weeks 7–10): N-P-K 0-3-3. Supplement calcium and magnesium if deficiency signs appear. Flush in week 9–10.
Amend soil with worm castings and kelp meal to feed microbes and enhance terpenes. A foliar spray of seaweed in early bloom can improve bud set without altering pH.
Pest & Disease Control
Inspect daily for spider mites, aphids, and thrips. Treat early with neem oil or insecticidal soap, covering leaf undersides. Use yellow sticky traps to monitor flying pests.
Ensure strong airflow to prevent mildew. Avoid overhead watering during flowering. Quarantine new plants 7 days before adding to the main grow.
Blueberry × Jack Herer Autoflower Harvesting & Curing
Harvest when 70%–80% of trichomes are cloudy with some amber. Cut branches, trim fan leaves, hang upside-down in a dark, ventilated space at 60–70 °F and 50% RH for 7–10 days.
Manicure buds and jar loosely in glass containers up to 75% full. “Burp” jars 5–10 mins daily in week 1, then weekly for 2–4 weeks. Use humidity packs to maintain 58%–62% RH.
Post-Harvest: Drying, Curing & Storage
After curing, store in airtight jars with humidity packs at 60–65 °F in darkness. For long-term storage, vacuum-seal in Mylar with desiccants. Label jars and check monthly to rebalance humidity.
Troubleshooting Common Issues
Nutrient Issues: Yellow leaves signal N deficiency; brown tips show nutrient burn. Correct by adjusting feed or flushing with pH-balanced water, then resume at half strength.
Environmental Stress: Heat stress causes leaf curl; light burn bleaches leaves. Raise lights, improve ventilation, and maintain temps below 80 °F. Use a humidifier if RH falls below 40%.
Watering & pH/EC: Overwatering droops plants; underwatering wilts. Water when top inch is dry. Keep pH 6.0–6.5 and EC 1.2–1.8 mS/cm.
